"The first computers were gigantic, filling rooms and requiring constant care and maintenance. [...] The computer stayed on the desk until the laptop computer, a smaller, more portable, but just as powerful machine, made it nearly obsolete. And then, the iPhone was released, followed shortly after by Android and the Palm WebOS, and the next step in computing was clear. What we did not immediately understand was if mobile computing was an accessory, or a replacement, for the traditional desktop machines." Jon-Buys at Ostatic believes the phone-becomes-computer paradigm is the next step.

I think in terms of ultra portability and desktop clutter removal projected keyboard is the future. Tactile feedback notwithstanding, audio feedback can certainly be provided.

Clearly, you are not a touch typist. When we say "feedback," we don't simply mean the feedback of pressing the keys though that is part of it and is a comfort factor. We refer to the fact that you're able to put your fingers on the home row of the keyboard and not move your hands from that position until you need to use the mouse. Those of us who can touchtype, we find the home row instantly and go from there. We do not look at the keyboard at all, we type entirely from muscle memory. We know where the home row is, we know where the letters are in relation to our fingers' default positions, and simply go from there. There is no virtual keyboard of any kind, either with audio feedback or without it, that will allow this. It's physically impossible to do this without having real, genuine keys until you can find a way to project tactile surfaces with a laser.
